Application filed; November 21,1914. Serial No. 873,290.

Be it known that I, JosErH Zunnmacltizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in the Process of Making Buttons from Ivory-Nuts and the like, of which the following is a specification. i

This invention relates to a process of forming buttons from slabs of ivory nuts or similar material.

In the drawings there is shown a series of views illustrating the successive steps of I the novel process referred to.

In the drawings, Figure '1 represents-a slab or section of an'ivory' nut 'or similar piece of material from which the new duplex blank is'to be out; Fig. 2 is a section through the same, showing the condition which exists after the'cutting facing tools have operated upon the slab'on'both sides,

the operative ends of such tools being shown in section on each side of the slab; Fig. 3 is a similar view showing the right "half of the 4 duplex blank with the appropriateholes or recesses drilled therein, the ends of the drills being shown in 'elevation; Fig. 4: is a similar view showing the left side of the duplex blank with the holes or recesses drilled therein, thedrills being shown in elevation; Fig. 5 is a sectional view of the slab illustrating the manner in which the duplex blank (also shown in section) is ejected from the slab afterit has been out therefrom; Fig. 6 is a section'showing the duplex blank severed to form two buttons,- the operative end of the severing tool being shown inelevation; Fig. 7 is a front elevation of the faces of the two buttons cutfrom the blank shown in Figs. 2, 3, 4,5, and6; Fig.

8 is a section showing a duplex blank in which the right and left hand halves are to 'material'of the thickness of two buttons and be formed of different diameters; and Fig. 9

is a front elevation of the faces of two buttons cut from such a duplex blank as is shown in Fig. 8.

to-back but united by a common strip of intermediate material which is subsequently to be removed; then'cutting out such duplex blank fromv the slab and finally severing the blank into two complete buttons.

More specifically described, in carrying out the preferred process, the blank is produced by first simultaneously partially cut ting away the edge of the buttons from opposite surfaces of the same slab, then subjecting the portions within the blank to the action of face forming tools, after which holes are drilled, first from one side, and then from the, other. The complete cutting of the edges from the material slab' is then made-so that the blank is severed from the slab and finally an inwardly tapering out is made, beginning at the center of the periphery of the severed blank, thereby cutting said blank into two buttons.

It is also important that the operation of forming the backs of the two buttons and severing the same should be conducted very soon after the blanks have been formed.

ess. -This is to moisten and soften them.

As the material is of'uneven density if it-is allowed to become dry and cool, it will not always assume the same shape or occupy the same volume if again heated and moise tened, and therefore it is desirable'to carry out the process while their temperature (induced by the steaming process and the heating action of the tools), is substantially unchanged' In the preferred form of apparatus for carrying it out which I amusing,

' onlytwelve seconds elapses from the time -the blank is made until it is finally severed and the finished buttons completed.

claim: I 1; As an article of manufacture, a duplex buttonblank comprising a piece of suitable having its opposite faces fashioned into the form of two button faces, therear sides of the individual blanks being integrally joined,

button-blank comprising a piece of suitable material of, the thickness of two buttons to be made therefrom and havingtheir oppo:

button faces, back to back, the outside periphery of each face being of adiiferent radius.

8. As an article of manufacture, a duplex button blank comprising a piece of suitable material having a cylindrical edge, concave on each face and provided with transverse holes.

at. As an article of manufacture, a duplex button blank comprising a piece of suitable material having a cylindrical edge, concave on each face and provided with transverse holes, the edge being stepped down on one side to a smaller diameter than the body of the blank.

5. The process of simultaneously forming a duplex button blank out of which to cut two buttons out of ivory nut or other suitable material, which consists in subjecting a suitable slab to the action of suitable facing tools, and thereby producing opposite faces, to the action of suitable drilling tools to form openings therein, and cutting away the edges around the faces from the slab to sever the duplicate blank from said slab.

6. The process of simultaneously forming a duplex button blank out of which to out two buttons out of ivory nut or other suitable material, which consists in simultaneously partially cutting away the edge of the buttons from opposite surfaces of the same slab, subjecting the same to the action of face forming and drilling tools in convenient succession, and completing the cutting of the edges from the material slab.

7. The process of simultaneously forming a duplex button blank out of which to cut two buttons out of ivory nut or other suitable material, which consists in subjecting the same to the action of edging tools on both sides of the slab, subjecting the same to the action of facing tools on both sides of the slab, and severing the same from the slab by the action of an edging tool.

8. The process of simultaneously forming a duplex button blank out of which to out two buttons out of ivory nut or other suitable material, which consists in simultaneously partially cutting the edges of the blanks from both sides of the slab and concaving the opposite faces of the material, drilling holes first from one side and then from the other, and completing the edge cutting to sever the blank from the slab.

9. The method of manufacturing buttons, which consists in forming a duplex blank of the thickness of two buttons, forming concave button faces in the opposite faces of said blank and separating into individual in the duplex blank to, simultaneously produce substantially convex backs to the individual blanks.

10. The process of forming two buttons simultaneously from the same piece of material, which consists in subjecting a suitable slab to the action of suitable facing tools,

the middle of the cylindrical body to form the two buttons and simultaneously cutting away a greater amount of material at the periphery than at the center.

12. The process of forming two buttons simultaneously from the same piece of material, which consists in simultaneously partially cutting away the edge of the buttons from opposite surfaces of the same slab, subjecting the same to the action of face forming and drilling tools in convenient succession, and completing the cutting of the edges from the material slab, and simultaneously cutting away a greater amount of material at the periphery than at the center to form the two buttons.

13. The process of forming two buttons simultaneously from the same piece of material, which consists in subjecting the same to the action of edging tools on both sides of the slab, subjecting the same to the action of facing tools on both sides of the slab, and severing the same from the slab by the action of an edging tool and simultaneously cutting away a greater amount of material at the periphery than at the centerto form the two buttons.

14. The process of forming two buttons simultaneously from the same piece of material, which consists in simultaneously partially cutting the edges from both sides of the slab and concaving the material, drilling holes first from one side and then from the other, and completing the edge cutting to sever the blank from the slab and simultaneously cutting away a greater amount of material at the periphery than at the center to form the two buttons.

15. The process of forming two buttons simultaneously from the same piece of mate rial, which consists in subjecting a suitable slab to the actionof suitable facing tools, to the action of suitable drilling tools, and cutting away the edges from the slab, and then, without allowing the blank to cool or dry, severing the blank so formed at the middle of the cylindrical body and simultaneously cutting away a greater amount of material at the periphery than at the center to form the two buttons.

16. The process of forming two buttons simultaneously from the same piece of mateamount of material at the periphery than 10 rial, which consists in subjecting a suitable at the center to form the two buttons.
